Neha went to a 'sale' to purchase some pants and skirts. When her friend asked her how
many of each she had bought, she answered "The number of skirts are two less than twice
the number of pants purchased. Also the number of skirts is four less than four times the
number of pants purchased."

Answer:
the number of skirts =0.and
the number of pants =1.
Step-by-step explanation:
let the number of skirts be =x and
number of pants be =y.
neha said that "the number of skirts are two less than twice the number of pants 0
purchased".
so,x=2y-2.
x-2y+2=0 . this is equation 1
and neha also said that "the number of skirts is four less than four times the number of pants purchased".
so,x=4y-4
x-4y+4=0. this is equation 2.
equation 2-1:
x-4y= -4
x-2y= -2
(here you have to do sign conversion)
the difference will be : -2y= -2
y= -2/ -2
y= 1.
sub y=1 on equation 1
x-2y= -2.
x-2 (1)= -2.
x-2= -2.
x= -2+2.
x=0.
